Primzahlen in Python

from math import sqrt
for i in range(2, int(sqrt(num)) + 1):
    if num % i == 0:
        print("Not Prime")
        break
    print("Prime")

# Note: Use this if your num is big (ex. 10000 or bigger) for efficiency
# The result is still the same if the num is smaller

Primzahl in Python

# This shows how we can use for + else using a break in between

for x in range(1,101):
# if you want to find whether a user input is a prime number
# use the following insted of the first for loop
# x = int(input("Type a number: "))
    for i in range(2, x):
        if x % i == 0:
            print(x, "is not a prime number.")
            break
    else:
        print(x, "is a prime number.")

# This will print all the numbers from 1-100,
# in the same line will print whether it is a prime or not

# if you use the user input method
# when you type 9, the output will be:
# 9 is not a prime number.

# when you type 7, the output will be:
# 7 is a prime number.
